PATRICK J. LUCEY, OF CHICAGO, ILLINOIS, ASSIGNOR TO LUCEY SLICING-MACHINE COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS.

SLICING MACHINE.

Application filed March 3, 1922. Serial No. 540,801.

To all whom it may concern. p

Be it known that I, PATRICK J. LUOEY, a citizen of the United States,and a resident of the city of Chicago, county of Cook, and State ofIllinois, have invented certain new and useful Improvements in SlicingMachines, of which the following is a specification.

My invention relates to new and useful improvements in slicing machinesof the type in which a reciprocating table moves to and fro along theside of a rotating knife.

In this type of slicing machine the operating means, which usuallyconsists of a flywheel or a crankwheel, is rotated in a right hand orclockwise direction (as viewed from the right hand side in Figs. 1 and2) thereby rotating the circular knife in a clockwise direction,indicated by arrow in Fig. '2, so that the cutting portion of theknife-edge will move in a'downward direction as it engages and slicesthe material fed to it by the reciprocating table. And if the operatorthoughtlessly happens to rotate the crankwheel and thereby the knife inthe contrary or counter clockwise direction which frequently occurs)then the cutting portion of the knife-edge, in its up ward movement,carries upwards with it the slices of material just severed and dropsthem at random instead of permitting the slices to drop in position inthe receptacle, asintended. And furthermore by such upward movement ofthe cutting portion of the knife-edge the material on the reciprocatingtable will be lifted and shifted sideways and the slices willconsequently vary in thickness." .Andsince most types of slicingmachines have a gradual movement of the reciprocating table during thecutting or feeding stroke while the crankwheel is being rotated in theintendedclockwise direction, and a rapid movement during the returnstroke, thenany reverse or counterclockwise rotation of said' crankwheelwill on the contrary cause the material to be fed to the knife with arapid stroke and will produce a slow return, justcontrary to themovements desired.

It is my object to obviate these unpleasant incidents resulting from anyaccidental counter-clockwise or left-hand rotation of the crankwheel orsimilar driving member, and to render such undesirable occurrencesimpossible by providing means in a slicing machine which will alwayscause the cutting portion of the knife edge to descend on the materialadvanced tosaid knife by the reciprocating table irrespective of thedirection of rotation of the crankwheel or similar driving means, andwhich means will simultaneously cause the table to move gradually to andalong the knife during its cutting stroke and rapidly during its returnstroke.

.This and other objects and advantages will become apparent from thefollowing description taken in connection with the drawings, in which,

Fig. 1 is a plan view of my invention applied to a slicing machine, withparts broken away;

Fig. 2 is a side view thereof, partly in section, taken on line 2-2 ofFig. 1;

Fig.4 is an enlarged sectional view taken on line of Fig. 2; and

Fig. 5 is an enlarged sectional view taken on line 5-5 of'Fig. 4,illustrating the clutch elements.

Inthe drawings I have shown my invention applied to a' slicing machineof well known construction, comprising a frame 10 provided with a feedtable 11, mounted to reciprocate on slide rails 12 and 13 which aresupported on pillars 14L and 15, respec tively, extending upwards fromthe frame.

.The machine comprises a circular knife 16 rotatably mounted on theupper part of the chain box or housing 17 by means of a knife shift18,which carries a sprocket 19 on one en I The gear mechanism fordriving the knife and table comprises a crown gear 21 fastened on avertical shaft 22 which is journaled in the frame and is connected atits upper end to a crank arm 23, a link 24 being pivoted to said arm andto one corner of the feed table, as shown at 25 in the drawings.
